为什么自己编译器上能跑出正常结果，但是在这里一直报错...

#include<stdio.h>
int main()
{
    double c;
    int k, n;
    scanf_s("%d", &k);
    n = 0;
    for (c = 0; c <= k; ++n, c = c + 1.0 / n);
    printf("%d", n);
    return 0;
}

scanf_s不是c++标准中的，请用scanf

#include <iostream>
#include <cmath>
using namespace std;
int main(){
    double n;
    cin>>n;
    double sum=0;
    for (int i=1.0;i<100000000000;i++){
        sum+=1.0/i;
        if (sum>n){
            cout<<i;
            break;
        }
    }
}

while循环可能会更好一些，但我用了for循环
